Moritte of the Frost + Altar of Dementia

Moritte of the Frost

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing Moritte of the Frost.
2. When Moritte of the Frost dies, it triggers its persist ability, returning itself to the battlefield as a copy of the creature with persist with two +1/+1 counters and one -1/-1 counter on it.
3. Remove one +1/+1 counter and one -1/-1 counter from Moritte of the Frost as a state-based action.
4. Resolve the activated ability from step 1, milling target player a number of cards equal to Morrite of the Frost's power.
5. Repeat.
